Industrial Flame Arrester Application Questionnaire

342 views

Published on

A flame arrester operate by removing heat from the flame as it attempts to travel through narrow passages with heat-conductive walls. The arrester will stop a high velocity flame head by absorbing heat from the flame head, which lowers the burning gas/air mixture below its auto-ignition temperature and creating an atmosphere where the flame cannot survive. Channels or passage are designed into the device to conduct heat outward but still allow the gasses to flow. Here is a document to help you apply the correct type for your requirement. Please always consult an applications expert (Belilove Company-Engineers - (510) 274-1990) prior to selection and installation.

Industrial Flame Arrester Application Questionnaire

  1. 1. FLAME ARRESTER APPLICATION QUESTIONNAIRE Definitions: Run-Up Length (L): pipe length on the unprotected side of the flame arrester (see diagram - tested with straight pipe) Run-Up Length Ratio (L/D): run-up length divided by pipe diameter The information below is required in order for us to help you choose the appropriate flame arrester model for your application.NEC Methane D C B A IEC IIA1 IIA IIB1 IIB2 IIB3 IIB IIC Pre-Ignition Pressure Pre-Ignition Temperature Maximum Pressure Drop Required Flow Max Allow Working Pressure Run-Up Length (L) Flange Size (D) L / D : OMER: Gas Group (circle one) L Groth in-line deflagration flame arresters must be installed at or within 10 pipe diameters of the source of ignition and are only approved for gas groups IIA1 / Methane, pre-ignition pressures at or below 15.7 psia, and pre-ignition temperatures at or below 140°F. Groth end-of-line deflagration flame arresters must be installed at or within 10 pipe diameters of the end of a vent pipe and are only approved for gas groups IIA / D, pre-ignition pressure at or below 14.7 psia (atmospheric), and pre-ignition temperatures at or below 140°F.
